Agitators are known tGerman Patent 1, 161, 795) which are fashioned as a coiled wire section in the manner of a spiral-shaped compression spring. Such agitators have the disadvantage that they must be normally manufactured from spring steel and permit intensive intermixing only with repeated shaking of the container, due to their configuration. The design must in each case furthermore be such that a certain tumbling motion of the spiral spring section is made possible, because otherwise no appreciable intermixing can occur in the zcnes between the outside periphery and the inside diameter of the container or in the inside of the spiral spring section. Therefore, it is also necessary to observe the maintenance of tolerances regarding the
2 0 outside diameter ~d the length of the wire section, if a jamming of the agitator is to be safely avoided.
Furthermore, known are agitators of the type mentioned hereinabove (DOS -~erman Unexamined Laid-Open Application 2, 127, 748), wherein perforated disks or cruciform parts are offset 2 5 with respect to each other in the axial direction and surround a tubular ~141749 inner part, However, such an arrangement has the disadvantage that the resistance of the shaker element against axial movement is likewise increased by the surface area of the disks, and that relatively large contact areas are produced between the lowermost disk and the container bottom, where the element can stick to the pigments of the paint, Detachment in such a case is possible only with great difficulties, or not at all.
Therefore, the invention has an object of constructing an agitator of the type mentioned above in such a way that intensive intermixing occurs in all zones of the container, even if the container is only slightly shaken to move the agitator.
The invention resides in that ribs are fashioned in the manner of vanes of a fan wheel and are uniformly distributed along the periphery of a hollow element, which latter element is constructed a a cylindrical tube, wherein the outer edges of the ribs are located on an imaginary cylinder, the diameter of which is smaller than the inner diameter of the container. This construction permits a simple manufacture of the agitator, for example as an injection-molded or die-cast part of plastic or of metal. Due to the ribs operating in the mLanner of 2 0 propellers, the construction ensures excellent intermixing, even with minor shaking. In this connection, it is very advantageous to arrange the outer edges of the r ibs on an imaginary cylinder, the diameter of which is slightly smaller than the inner diameter of the container, because thereby also the marginal zones of the liquid provided in the container can 2 5 already be affected with a single upward and downward motion of the agitator and are not initially intermixecl by repeated tumbling motions of an agitator.
It is also advantageous that the area coming into contact with the bottom of the paint-filled container, corresponding essentially only to the end faces of the ribs, can bekept at a very small size. Therefore, sticking of the agitator need not be feared even when the unit is unused for a relatively long period of time.
These non-stick properties can be still further improved by selecting the axial length of the enveloping cylinder for the outer edges of the vanes to be larger than the length of the tube, and by extending the leading edges of the vanes at an angle to the longitudinal axis inwardly, By this construction, there result only spot-like contact points in the outermost region of the vanes, so that the contact areas with the bottom of the container of the touch-up stick are reduced to a minimum, l~he novel design therefore secures in any event the free movability of the agitator within the paint container.
It is also advantageous if, in such an arrangement, for -reasons of manufacturing technology, the fan blades proper are fashiored as straight blade vanes oriented merely at an angle with respect to the axial extension of the agitator. Such an agitator can be produced in a very simple way, for example by the die-casting method, fromametal.
It has proved to be sufficient and advantageous, according to a preferred embodiment, to provide four blade-like ribs, the two leading sides of which are oriented at right angles to the tube wall and are offset with respect to each other in the peripheral direction. In this 2 5 embodiment, flow channels can form between the blade-like ribs;
if the length of the agitator is approximately designed so that it corresponds to one-half the length available in the container for the axial movement of the agitator, these flow channels then effect, with a one-time shaking step, already a sufficient turning of the agitator, translated into the desired mixing rnotion of the liquid.
This novel construction of the agitator thus permits a secure, perfect guidance of the agitator in the container, a simple manufacture, and an excellent mixing effect, without the brush provided in the container being subjected to damage by or contact with the moving 1 0 agitator.
These and other objects, features and advantages of the present invention will become more apparent from the following description when taken in connection with the accompanying drawings, which show, for purposes of illustration only, plural embodiments in accordance with the present invention.

DETAILED l:)ESCRIPTION OF THE PREFERRED EMBODIMENT
Figure 1 shows a cylindrical container 1 of a touch-up stick to repair paint damage on automobiles, wherein a sealing plug 2 is inserted fixedly joined to the top rim of the container 1. The sealing stopper ~ carries an external thread 3 on which a screw cap 4 is provided constructed in a conventional manner. This screw cap 4 has a conical extension 5, wherein a brush 6 is fixedly clamped. The screw cap furthermore has an inner hollow space 7, which is likewise conventional, this spacing being covered at the top by an additional cap 8. This hollow space can contain, for example, filling material or some other material required to execute the paint repair wor~.
An agitator 9 is inserted in the container 1, this agitator serving for stirring up the varnish paint present in the container 1 before the repair wor~ is started. This is done by shaking the container 1 in the sealed condition to and fro in the axial direction, 2 0 whereby the agitator 9, due to its inertia, executes an axial movement within the container 1 The agitator 9 consists, as can be seen particularly also from Figure 2, of a cylindricaltube 10; ribs 12 extending helically with respect to the longitudinal axis 11 are provided along the periphery 2 5 of this tube and are fashioned in the mar~er of the blades of a fan wheel.
In the illustrated embodiment of Figure 2, four ribs 12 are arranged, the upper end faces 13 of which are arranged, respectively offset by 90 with respect to one another) on the periphery of the tube 10, namely in such a way that they are disposed with the upper end face lOa of the tube 10 in a radial plane extending perpendicularly to the longitudinal axis 11. The lower end faces 14, which are likewise in alignment with the lower end face of the tube 10, are respectively offset by about 90 in the peripheral direction with respect to the associated upper end faces of each rib, so that the inlet cross sections of the flow channels formed betweenthe ribs 12 are likewise opposing one another, offset by about 90.
The total length 1 of the tube 10 and of the ribs 12 is selected so that it corresponds to approximately one-third or up to one-half of the entire length L available in the container 1 for the axial movement of the agitator 9. By means of this construction, a single shaking step is, in some cases, sufficient to perfectly intermix the paint contained in container 1, due to the twist exerted by the agitator. It is, of course, also possible to orient the ribs 12 at a lesser angle to the longitudinal axis 11, so that the leading sides 13 and 14 of each rib are 2 0 offset with respect to one another, for example, only by about 45 or 60.
The governing factor is that the ribs are to act on the varnish paint in the manner of fan blades when the agitator 9 executes an axial movement--caused by shaking of the container 1-- within the c altainer 1.
The outer edges 15 of the ribs 12 are, in this embodiment, 2 5 on an imaginary cylinder, the diameter of which is slightly smaller than the inner diameter of the container 1. Thereby the agitator can be perfectly guided within the container 1 without having to fear damage to the brush 6. In this case, it is also advantageous that the entire inner region of the container 1 is under the effect of the twisting action of the agitator 9 during a shaking process, wherein the interior of the tube 10 participates in the mixing procedure by the fact that the lower end of the brush 6 moves in the inner space of tube 10 relatively to the latter. The novel arrangement therefore permits an excellent intermixing of the paint in the container 1 during shaking.
The agitator 9 can be produced in a very simple manner as a single part by use of either the injection-molding method or die-casting method, There are no molding problems. The material used for manufacturing the agitator can be metal, e. g., cast zinc, or also a synthetic resin.
I 5 The agitator 9' shown in Figure 3 consists of an inner, cylindrical tube 10 ', ribs 12 ' being provided along the pe riphe ry of the tube extending helically with respect to the longitudinal axis 11 of the tube. As in Figures 1 and 2, these ribs are constructed in the manner of the blades of a fan wheel and are arranged in this fashion. The leading sides 13 2 0 of each of the ribs 12' are not arranged in a common plane flush with the end face of the tube 10' in contrast to the embodiment of Figures 1 and 2 Rather, these leading sides are arranged, as can be seen particularly from Figure 4, at an angle a with respect to the longitudinal axis 11', namely in such a way that these leading sides 13', starting from the 2 5 imaginary enveloping cylinder having a length L covering the outer edges 31 1~1~7~5~
15' of the individual blade-like ribs 12', are extended obliquely inwardly back to the length 1 of the tube 10'. Therefore, in the two illus-trated embo d i m e nts of Figures 3 and 4, there are, on the two outermost boundaries of the agitator 9' at the end face, which boundaries are located at a mutual spacing of L, only four approximately point-like locations 20 on each side which can come into contact with the bottom of the paint container when using the agitator 9' in cylindrical paint containers according to Figure 1. The contact areas between paint container and agitator 9' are thus reduced to a minimum. The novel agitator thus cannot stick together with pigments of the paint after a ~latively long resting period on the bottom of the paint container.
As can be seen from Figure 4, this embodiment differs from Figure 3 only in that the ribs 12 constructed as fan blades are inclined at an angle to the longitudinal axis 11, but are not inherently twisted. It has been found that the force component effecting a shaking up of the paint is large enough to attain sufficient intermixing even without twist of the ribs. However, if the agitator shown in Figure 4 is made of one piece, for example of a metal casting, the shape required for this purpose can be manufactured in a substantially simpler 2 0 manner if the blade twist is eliminated.
While we have shown and described only several embodiments in accordance with the present invention, it is understood that the same is not limited thereto but is susceptible of numerous changes and modifications as would be known to those skilled in the art, given the 2 5 present disclosure, we therefore to not wish to be limited to the details 1~417~9 shown and described herein but intend to cover all such changes and modifications as are encompassed by the scope of the appended claims.

Furthermore, known are agitators of the type mentioned hereinabove (DOS -~erman Unexamined Laid-Open Application 2, 127, 748), wherein perforated disks or cruciform parts are offset 2 5 with respect to each other in the axial direction and surround a tubular ~141749 inner part, However, such an arrangement has the disadvantage that the resistance of the shaker element against axial movement is likewise increased by the surface area of the disks, and that relatively large contact areas are produced between the lowermost disk and the container bottom, where the element can stick to the pigments of the paint, Detachment in such a case is possible only with great difficulties, or not at all.

Therefore, in the two illus-trated embo d i m e nts of Figures 3 and 4, there are, on the two outermost boundaries of the agitator 9' at the end face, which boundaries are located at a mutual spacing of L, only four approximately point-like locations 20 on each side which can come into contact with the bottom of the paint container when using the agitator 9' in cylindrical paint containers according to Figure 1. The contact areas between paint container and agitator 9' are thus reduced to a minimum. The novel agitator thus cannot stick together with pigments of the paint after a ~latively long resting period on the bottom of the paint container.
As can be seen from Figure 4, this embodiment differs from Figure 3 only in that the ribs 12 constructed as fan blades are inclined at an angle to the longitudinal axis 11, but are not inherently twisted. It has been found that the force component effecting a shaking up of the paint is large enough to attain sufficient intermixing even without twist of the ribs. However, if the agitator shown in Figure 4 is made of one piece, for example of a metal casting, the shape required for this purpose can be manufactured in a substantially simpler 2 0 manner if the blade twist is eliminated.
While we have shown and described only several embodiments in accordance with the present invention, it is understood that the same is not limited thereto but is susceptible of numerous changes and modifications as would be known to those skilled in the art, given the 2 5 present disclosure, we therefore to not wish to be limited to the details 1~417~9 shown and described herein but intend to cover all such changes and modifications as are encompassed by the scope of the appended claims.

1. Agitator for cylindrical containers filled with paint or varnish, especially for touch-up sticks to repair paint damage on automobiles, said agitator being constructed as a tubular hollow member guided in the container for reciprocating shaking movement in the axial direction, surrounding a brush attached to a cap and exhibiting radially outwardly projecting ribs that are uniformly distributed about the periphery of the hollow member and have their outer edges located on an imaginary cylinder the diameter of which is slightly smaller than the inner diameter of the container, characterized in that the ribs are inclined with respect to the longitudinal axis of the hollow member in the manner of blades of a fan wheel.
2. Agitator according to claim 1, characterized in that the ribs are twisted helically with respect to the longitudinal axis of the hollow member.
3. Agitator according to claim 1, characterized in that four ribs are provided having two leading sides which are respectively mutually offset in the peripheral direction, but extend perpendicularly to a tangent placed on the outer diameter of the hollow member.
4. Agitator according to any of claims 1 to 3, characterized in that the length of the ribs corresponds to approximately one-third to one-half of the length available in the container for the axial movement of the agitator.
5. Agitator according to claim 3, characterized in that the leading sides respectively are in alignment with the end faces of the hollow member.
6. Agitator according to any of claims 3 or 5, characterized in that the hollow member is moulded as a single part with the ribs.
7. Agitator according to claim 1, characterized in that the axial length of the imaginary cylinder is greater than the length (m) of the tube and the leading edges of the ribs extend inwardly at an angle with respect to the longitudinal axis.
8. Agitator according to claim 7, characterized in that the ribs are fashioned as straight vane blades but are arranged at an angle relative to the longitudinal axis of the agitator.
9. Agitator according to any of claims 1 to 3, characterized in that the length of the ribs corresponds to approximately one-third to one-half of the length available in the container for the axial movement of the agitator, the leading sides respectively being in alignment with the end faces of the hollow member.
10. Agitator according to any of claims 1 to 3, characterized in that the length of the ribs corresponds to approximately one-third to one-half of the length available in the container for the axial movement of the agitator, the leading sides respectively being in alignment with the end faces of the hollow member, the hollow member being moulded as a single part with the ribs.
